What's hot

• Exclusive platinum technology in the center electrode for quicker starts, smoother acceleration and increased fuel efficiency
• Factory-set gap ¿ once the proper gap is set, there's no need to re-gap
• Contains one spark plug

• Factory pre-set gap allows for easy installation that never requires adjustment
• Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• Revolutionary surface air gap firing technology featuring Bosch's unique four ground electrode design delivers the most powerful spark for the most efficient combustion and optimum horsepower without increasing the voltage requirement
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance

• Extremely durable under high heat
• Features superior anti-corrosion and anti-seizing properties
• Constructed from durable material

• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty
• Significant potential power increase: > 6% to 12% (depending on engine class)
